What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and plumbing fixtures — is taken out and replaced with a professionally installed shower unit. The complexity of the project is shaped by your existing bathroom footprint, your design preferences, and whether you need to expand the shower's footprint beyond the original tub's location.
On a technical level, the work involves capping the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower pan with a correct slope toward the shower drain. New waterproofing membrane is laid down before any surface covering goes on. Plumbing is rerouted to accommodate the new showerhead position and any body sprays, handheld wands, or rain heads you add.
The finished product is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done correctly is not just website a visual change — it is a fundamental transformation to your bathroom's plumbing, waterproofing, and layout.

The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A project consultant comes to your bathroom to assess your existing space and infrastructure. We go over your wishlist and timeline so the scope of work aligns with exactly what you need.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are demolished and cleared. Supply and drain lines tied to the old tub are disconnected, capped, or rerouted to set the stage for the updated fixture configuration.
- Structural Prep and Moisture Barrier Installation — This is widely considered the most important stage of a tub to shower conversion. New waterproof backer material is fastened to the structural framing, and a full waterproofing membrane is rolled or troweled on across all wet surfaces. The drain area is pitched properly to avoid standing water.
- Installing New Shower Plumbing — Licensed plumbers or our experienced crew set the new rough-in plumbing according to your chosen layout. Whether you selected a standard showerhead or an upgraded fixture package, everything is positioned at this stage.
- Finishing the Shower Walls and Floor — Our finish crew apply your selected finish material using the correct adhesive and grout system. Every seam is sealed and inspected before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your design choice, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is secured correctly to provide a solid, long-lasting result.
- Quality Check and Project Sign-Off — Once everything is complete, we conduct a room-by-room walk-through. Every seam at the perimeter are finished with flexible waterproof sealant. We review with you the finished shower and confirm everything looks and functions as planned.
